Who comforteth us in all our tribulation, that we may be able to comfort them which are in any trouble, by the comfort wherewith we ourselves are comforted of God. – 2 Corinthians 1:4

Know, my dear sister, that by thy sorrows the Lord has drawn out thy sympathies. Thou, my dear brother, know that by the discipline which has chastened thee, thou hast learned to be a comforter. Say you, then, that you cannot do anything? I know a few secrets about you that you forget. You do not reckon yourself up as we reckon you. Did you not try to cheer a poor neighbour the other day by telling of the Lord’s goodness to you when you were very sick yourself? How started from your eye that tear most sacred shed for a fellow-creature’s pain? Is it not your habit, poor sufferer as you are, to let drop just a few words for your Master to others in a like condition whenever you can? You tell me that you cannot do anything. Why, dear hearts, the refreshing of God’s saints is one of the highest works in which anyone can be occupied. God will send prophets to His servants at times when they need to be rebuked; if He wants to comfort them He generally sends an angel to them, for that is angel’s work. Jesus Christ Himself, we read, had angels sent to minister to Him. When? Was it not in the garden of Gethsemane, when He was bowed down with sorrow? Comforting is not ordinary work: it is a kind of angelic work. “There appeared unto Him an angel strengthening Him.” A prophet was sent to warn the Israelites of their sin; but when a Gideon was to be encouraged to go and fight for his country, it was the angel of the Lord that came to him. So I gather that comforting work is angel’s work. You, dear kind Christian men and women, who think that you are not able to do anything but to condole or to console with cheery words some souls cast down and sore dismayed, you are fulfilling a most blessed office, and doing work which many ministers find it difficult to perform…God’s tried people comfort each other con amore; they take to the work as a fish to water. They understand the art of speaking a word in season to him that is weary, and when this is the case they may not complain that they are doing nothing. ~ C.H. Spurgeon
